Jerry (1821 – 14 May 1851) was a British Thoroughbred racehorse and sire best known for winning the classic St Leger Stakes in 1824. In a racing career which lasted from 1824 until 1827 he ran ten times and won five races. Unraced as a two-year-old, he was beaten on his first appearance in 1824 but then won the York St Leger and the XYZ Stakes at Newcastle before defeating twenty-two opponents in the St Leger at Doncaster. Jerry missed the entire 1825 season and showed little form in 1826, but won twice as a six-year-old in 1827. He was retired to stud, where he proved to be a successful sire of winners.
